The specific embodiment

With reference to Fig. 1, the base cloth and the circle snap-fit element portion of the primary structure that only links parts as card of the present invention described.Only link in the main part 1 of parts at the card of the present invention shown in Fig. 1 (A); Base cloth 2 whole width are W; Have the 1st first type surface 3 and the 2nd first type surface 4; With the upright circle snap-fit element portion 5 that is provided with of width w, the both sides of circle snap-fit element portion 5 are such for waiting the width dimensions that will enclose snap-fit element portion 5 and the linking part 7 performance functions that kind of covering binding as being used for through making shown in Fig. 3 (A) in the 2nd first type surface 4 sides.On the other hand, only link among the main part 1' of parts at the card shown in Fig. 1 (B), in the 2nd first type surface 4' side, except the ear of two side ends, the roughly whole width that spreads all over base cloth 2' is provided with the circle snap-fit element 5' of portion for thirty years of age.In addition, other forms of main part that only link parts as card have been omitted diagram, but also can be for not being that both side ends at base cloth forms ear and spreads all over the upright form that is provided with circle snap-fit element portion of whole width.The main part that this card only links parts can be that Rack obtains through the structure cuts that will found the wider width that is provided with the circle snap-fit element.

Main part 1 such folding as Fig. 3 (A) shown in that banded card only links parts is two so that the 1st main surface side becomes the inboard, at the regulation position through make, thermal welding or formation the 1st first type surface Fixed Division 8 each other such as bonding.Has blank part 10 an interior week in cylindrical portion 9.In addition, Fixed Division 8 also can be formed by the portion of sewing up to covering.

In addition, shown in Fig. 3 (B), only can make by circle snap-fit element portion 5 forms cylinder, within it insert in week flexible bar-shaped core 10R, as required the periphery and the 1st first type surface of the bar-shaped core of flexibility passed through affixed structures such as bonding agent again.Flexible bar-shaped core 10R in Fig. 3 (B) illustration satisfy the situation of external diameter in the interior week of cylinder; As long as but have core function, be about to the function that circle snap-fit element portion that card only links the main part of parts draws in to the spacer forming side reliably, also can be the structure of thinner external diameter.

The base cloth of the circle snap-fit element of using in the present invention be braiding fabric or weave fabric which kind of can.But the card that weaves fabric base cloth only links parts and considers it is preferred from the good aspect of retractility, particularly preferably is on base cloth and weaves the circle snap-fit element portion that forms the circle snap-fit element through La Sheer.The fabric card of weaving that warp thread, weft yarn and loop yarn weaving are obtained only links parts because the cloth ground of base cloth is organized firmly, so flexibility is lower, has boundary aspect curve-like that is being suitable for complicacy and the curved groove.Card with circle snap-fit element of La Sheer braiding only links yarn and the braiding structure that parts are easy deformation, and cloth ground is organized as loose structure, and the gap between knitting yarn is bigger, is easier to so be out of shape.

Below, the situation of enclosing snap-fit element with braiding on the fabric base cloth of braiding is that the center describes.

The fiber that in circle snap-fit element portion, uses uses polyamide-based fiber, polyester fiber, TPO fiber etc. so long as the fiber that in common cloth and silk, uses is just passable.In addition, preferably multifilament also can mix monofilament in multifilament.The multifilament that constitutes circle preferably will be preferably 5~50, will be more preferably 10~40, more preferably 15~35 rhizoids are drop-down neat and form multifilament, so-called living yarn in non-twist straight condition.As the thickness of multifilament, preferably 100~250dtex.On the other hand, as the multifilament yarn of the grey cloth that constitutes circle snap-fit element portion, preferably 200~400dtex, silk number are 50~150 false twist processing yarn or itself and twist yarn.

Circle snap-fit element portion uses known woven cloth manufacturing installation through the known method manufacturing.Circle snap-fit element portion by base cloth be formed on a lip-deep circle snap-fit element portion and constitute.The width (width of base cloth) of circle snap-fit element portion is suitably selected according to the size of liner component, the width and the degree of depth of groove, but 10~80mm normally.The height of circle snap-fit element portion and upright establish density as required engage the power decision with dogging closes element portion, but highly be that 1~5mm, the upright density of establishing are (under the situation of multifilament, will be counted by the circle that multifilament constitutes be 1) 20~80/cm 2Be preferred.The surface that circle snap-fit element portion also can be formed on base cloth on the whole.But; Of the back; Be not be present in surface circle snap-fit element portion on the whole whole participate in the slot part bottom surface that is located at liner component on dogging close in the engaging of element portion; So more preferably only on the central portion alongst of base cloth, form, engage effectively so that it closes element portion with dogging on the slot part bottom surface that is located at liner component.

The retractility of circle snap-fit element portion (on a surface, being formed with the base cloth of circle snap-fit element) is estimated with expansion and contraction and telescopic resilience rate.Expansion and contraction is more than 3% on vertically (length direction) preferably, more preferably 4~15%, and the telescopic resilience rate is preferably more than 45%.

The expansion and contraction and the telescopic resilience rate of circle snap-fit element portion (face fastener) are obtained as following.On the free end of the vertical wide circle snap-fit element of the Tcm portion that keeps, apply the initial load (2.5g/cm) of T * 2.5g, measure the length (raw footage (a)) after 30 seconds.Then, apply the load of T * 250g (250g/cm), measure the length (length during load (b)) after 30 seconds.Load is removed, place after 2 minutes, apply initial load once more, measure the length (load experience back length (c)) after 30 seconds.Expansion and contraction is value, [ 100 * (the b-a)/a ] that deflection removes with raw footage during with load, and the telescopic resilience rate is value, [ 100 * (b-c)/(b-a) ] that deflection removes during with load with amount of recovery.

In the present invention, preferably use the circle snap-fit element portion that forms base cloth and circle snap-fit element through the La Sheer braiding.La Sheer braiding circle snap-fit element portion uses known La Sheer knit unit through the known method manufacturing.

On the face (the 1st first type surface) that is opposite to face (the 2nd first type surface), resin bed can be set with circle snap-fit element portion.Resin bed is formed on central portion and/or the both ends along the length direction of circle snap-fit element portion.The resin bed (resin bed A) that is formed on the central portion is discontinuous in the longitudinal direction.The resin bed (resin bed B) that is formed on the both ends both can in the longitudinal direction continuously also can be discontinuous, but preferably continuous.

Resin bed A has the effect that circle snap-fit element portion is strengthened from the back side.If strengthen through resin bed A, then will enclose the dogging that snap-fit element portion is pressed on the slot part bottom surface that is located at liner component easily and close on the element portion, can access more firm engaging, so be preferred.Become at the slot part of liner component two dimension ground, dimensional topography under the situation of complicated shape, card only links circle snap-fit element portion that parts, particularly card only link parts and forms part and need freely be out of shape according to the shape of slot part peristome.For this reason, resin bed A forms in the longitudinal direction discontinuously.If make discontinuously, the distortion that then is formed with the part (have overleaf circle snap-fit element portion) of resin bed A becomes easily, and the operation that card is only linked in the slot part of shape that parts are pressed into complicacy becomes easy.

Two resin bed B form and are used for when card only links the use of parts, being installed to the covering linking part on the covering.In addition, will block when only linking in the slot part that parts are pressed into liner component, and have to block and only link parts and remain linearity or forniciform effect corresponding to the shape of slot part.Thus, the fixed operation of covering becomes easy, in addition, and can be covering is correctly fixing along slot part.

The resin that is used for forming resin bed A and B is soft, preferably with the fiber that forms circle snap-fit element portion compatibility is arranged.Corresponding to polyester fiber or Fypro, can use synthetic rubber, polyurethane, soft polyester, soft polyamide, flexible polyolefins resin, allyl resin etc.

Resin bed A and B are through known method such as for example coating process (hot melt, extrusion etc.), bonding method, burning-on methods, through applying 50~300g/m under the state that above-mentioned resin is entered into the base cloth that encloses snap-fit element portion in a part 2And form.The width of resin bed A and B is suitably determined by the width that card only links parts, but distinguishes preferably 3~30mm.Thickness is 0.1~4mm preferably.They of the width of resin bed A and thickness and resin bed B both can be the same or different, and width and the thickness of two resin bed B also both can be the same or different.In addition, resin bed A and B both can card only link discontinuous on the width of parts also can be continuous.

Rectangular circle snap-fit element portion preferably has the morphotropism of the degree of the fixed operation of enough carrying out covering easily and accurately.For this reason, the time preferably with the flexibility of the base cloth of circle snap-fit element portion, the flexibility of resin bed A and B also is appropriate.The flexural resistance of base cloth of part that does not form resin bed is preferably below the 20g, more preferably 10~20g, more preferably 15~18g.In addition, the flexural resistance of part that is formed with resin bed A or B is preferably more than the 25g, more preferably 25~80g, more preferably 30~60g.Above-mentioned numerical value all is the value of the width of banded base cloth.If in the above-mentioned scope, then only to link parts can be not too not soft and handle and be easier to for card, and in addition, morphotropism is appropriate, makes the card that is installed on the covering only link parts easily and is out of shape along groove.

Flexural resistance uses (strain) Daiei science precision instrument to make made flexural resistance testing machine " HOM-200 " measurement as following.The test portion that is formed with resin bed of width 40mm, length 200mm or the test portion (base cloth) that do not form resin bed carried put in the slit (width 20mm) of flexural resistance testing machine, so that its length direction meets at right angles.Then, with the push plate of width 2mm downwards to the test portion imposed load.Measure test portion from the slit load during faces downwards distortion 10mm, as flexural resistance.Measurement pushes from the 1st face side.
